FASTENING FOR WOVEN-WIRE FABRICS.

SPECIFICATION forming part of Letters Patent No. 238,982, dated March15, 1881. Application filed February 3, 1881. (Model) To all whom it mayconcern Be it known that I, J OHN N. STEVENSON, of Chicago, in the Stateof Illinois, have invented certain new and useful Improvements inFastenings for Woven-Wire Fabrics; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accon'ipanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to a fastening intended to more closely, neatly,and permanently secure wire fabric to bed-rails, and to offer no retreatfor vermin.

It consists, first, in a metal plate or cap adapted to be screwed overthe flattened fabric, binding the same to the rail, and provided with amarginal flange, which is forced into the wood of the rail, whereby theadmission of bugs beneath the plateis prevented; second, in thecombination ofparts, as will be hereinafter more fully set forth andspecifically claimed.

In the drawings, Figure 1 is a transverse section of an end rail of abed-bottom having woven-wire fabric secured thereto by my improvedfastening. Fig. 2 is an exterior perspective view of the rail andfastening; and Fig. 3 is a view of the under face of a metal angleplate,showing the marginal flange thereon.

Ais the woven-wire fabric. B is the wooden rail. 0 is theclamping-plate, and D is a body of felt or similar material insertedbeneath the plate 0 and over the ends of the fabric-wires. The wire endsare flattened down upon the rail, and bent down over the outer angle,1), and secured bylarge tacks. The strip D, of felt or heavy cloth, isthen laid over the wire and beneath the plate, and the latter issecured, by screws or otherwise, in the position shown, with its inneredge and that of the felt flush with the inner vertical edge of therail. In addition to the security afforded by the felt strip for theexclusion of vermin, the plate has a marginal flange, f, which, infastening the plate, is forced into the Wood of the rail, therebyclosing the openings otherwise produced by the wires. When such flangeis present and the plate is an angle-plate, the felt strip need notextend down upon the vertical surface of the rail, though it is betterin any case to employ a strip wide enough to fill the entire spacebeneath the plate, as shown in Fig. 1.

I prefer that the plate be double-flanged or angular, as shown in theseveral figures of the drawings, and for the purpose of giving greatersecurity to the fastening I provide the sharp longitudinal corrugationsc on the inner vertical face of the plate shown in Fig. 3, so that thewire ends, being bent over the angle 1) of the rail, are unevenlypressed by the corrugations, and thereby more firmly held. The angleform of plate has the advantages of greater neatness and of greatlyadding to the strength of the rail without materially increasing itssize.

The above-described devices, when properly applied, are sufficient toexclude vermin from between the rail and clamp-plate; but as, in thenecessarily cheap manufacture of bed-bottoms, defects in theconstruction or applica tion of the plate are likely to occur, Ipropose, for the purpose of still further assuring the end desired, toapply to the felt some one of the numerous powders or other meparationscalculated to repel or destroy vermin-pf the kind which usually infestbeds. applied in solution or in powder, the open texture of the feltwill readily admit the material, and when compressed will retain it.

Having thus described my invention, I claim 1. The metal plate G,provided with the margin al flange f, in combination with the woodenrail B and fabric A, substantially as described.

2. The angle-plate 0, having the corrugations 0 in its inner verticalface, and the marginal flange f, as an improved article of manufacture.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
